A 3.98 g sample of solid NaBr (s) is dissolved in 361 mL of water in a coffee cup calorimeter. Once all of the NaBr (s) is dissolved in the water, the final temperature of the solution is found to be 30.04°C. If the initial temperature of the water in the calorimeter was 21.84 °C, calculate the calorimeter constant (in J/K) for the coffee cup calorimeter.

The heat of solvation of NaBr (s) is -0.60 kJ/mol.
